f citizen oft the United States, residing in the Vlat-ch from theoutside of thedoor, and con? town of 'East Haven, county of New Haven,`

and State of Connecticut, have invented certain new and usefullmprovements "in,y Locks, of which the following afull, clear,` andexact description.y A l This invention relates to locks, and' more eparticularly to latch bolt locks for fschoolhouses and similarbuildings,havingrneans 1\'\='hereby the'latchv'bolt maybe ,held back yiny f the case When retracted by ther key.k 1n' yanV application iled July2 0, 1912, Serial No; 710,570, resul-ting in the grantof Lettersf latentNo. 1,126,560, January 26, '1915,'1

have described a lockk having niechanismf operable by a key forretraotinglthe latch bolt, and holding yit in retractedposition, whichmechanism Was'primarily devised for the vconvenience of the janitorofthe build-f ing, so thathe could readily "stop backtheV latch. lVhenit' was merely desired to unlock" the door temporarily, 4the janitorcould, by a reverse movement oit 'the key, readily-'release the latch,after it 'had been` lockedfin" retracted position'as a neicessjaryresultof `its Y retraction. Certain doors ofthe bu'ildin, however, are in useby the teachers, and in entering such doors, the teache'rqoitenomits togive 'the lreythe necessary `4movement to e release the retracted latch,whereby thev doorslarefrcquently left unlock-ed at Vtimes whenI theyshou'ld'be locked against intrusion from the outside. Moreover, ithasbeen found. desirable to-prevent the stopping back kof Ithe tine thisfunction to mechanism-i` operable,` `from the inside oiithe door,vthough permit-' ting retraction ofthe latch from either side.

rThe primary objects oi the presentjinvenj tion are |to meet thek aboveconditions; to: provide a latchV bolt lock-"havingavbolt, re-y tractableby akey or key's'inserted ateach` side oi' the dooigiinechanism beingprovided 'tor stoppingback the latchy When-it re? f tracted from oneVside Without stopping'it` back Whenit is retracted from ythe other side;to provide a locx' having a key for-re.

Referring to the drawings, the case spring 13. The stem 14 of the latchbolt VVcarries a head l5,L engaged by-a lever 16,

adapted to beoperatedbya lifter 1T,'Which is inturn actuatedby aninsidethumb'piece,

pushbanorother mechanism (not shown). Thewparticular .means forretract'ing the latch boltmanually from thev inside of thervdoorfisiiinrnaterial;`P In-the particularl lock .selected for'.illustration," the retraction of the bolt from the outside` ofthe dooris confL fined tothe key, but thisv isilikewise an immaterial Ifeature.

fllhe means for retractingjthe latch bolt, by meansof a key, comprises alatch bolt retractinglever 20,'vpivoted in the'case'at 2l,

yvithfthe ycrosshe'ad 15 of the bolt. --The retracting lever 20ispi'ovided With a projec-` F 'gT 6 is a detaili-otthemain de'tent lever1o of the lock, having thek faceplate l1, contains e a latch lbolt 12,normally l'projected by a so f and having one extremity thereof engagedico ing'the arm 24: tothe right; This arm, by

engaging the projection 23, carries With it j in its ,movement 'theretracting lever 20, wherebythe Vlatch bolt i's'retracted. Acyl- Il 1Vcreate a pointed projection as shown.

end 3l loosely rests on, and is supported by,

a lateral projection 3% on the lever 20. The parts are so arranged thatwhen the bit 30 is turned in an anti-clockwise direction, with respectto F ig. l, it will be unable to Contact Ywith the projection 2a oflever 25, but will,

on the other hand, depress the lever 32 and actuate the lever 2O toretract the latch bolt without moving the lever 25 to any appreciableextent, as shown in F ig. 2. l have not considered it necessary toillustrate the pin tumblers with which the cylinder locks 23 and 29 areprovided, as this ieature is Well understood in the art.

The arm 2e of the lever 25 is made of special shape so that as said armis actuated by thebit of the inside cylinder lock 28, it may operate tohold the latch bolt in its retracted position. To this end, the edgeportion of the arm 2a, coactiug with they projection 23 of the latchbolt lever, is formed with a shoulder 39, having inclined edges l0, atl,directed at an angle to each other,-.to As the latch bolt is retractedby the lever' 25, the edge t0 of said Shoulder or projectionbearsagainst tie projection 23, as the arm 24: moves toward the right Withrespect to Fig. l.y As the movement of the arm 2e continues, theshoulder 39 and projection 23 move relatively to cach other in such ainanner that as soon as the latch bolt has been fully retracted, theprojection 23 on `the 'latch bolt lever passes the apex of the shoulder39,4 andV snaps into position against the edge al oil` said shoulder,whereby the lever and the latch boit l2 are locked in retractedposition. n order to increase the security with which the latch bolt isheld in this position, the detent lever-25 is provided with a rearwardlydirected extension which, as the projection 23 passes from one side tothe other oiE the shoulder 39, snaps into position front of thecrosshead i and engaees said crosshear` irictionally, as shown in i*igs. 3 and il. in this manner, the latch bolt is held securely inretracted position. and it will remain in such position Until the bit 2Tis rotated in a direction opposite to that lirst indicated, in order tocause the abutment of the bit 27 iinstithc opposite side the j)rojection 2st and the release oi' the lever whereupon the parts Will berestored by the latch boltspring to the initial position.

lVhen the latch bolt has been locked in retracted position by the detent lever 25, it

will, preferably, be releasable by a key inserted at the outside of thedoor, as Well as by a key inserted at the inside. The actuation of thelever by the bit 30, as the latter is moved in an anti-clockwisedirection with respect to `Fig. l, is prevented by the means alreadydescribed, but there are no means shown for preventing the release ofthe lever 25 by contact of the bit 30 with the projection 24;, as saidbit is moved in a clockwise direction with respect to F ig. 3.Preferably, the inside and outside cylinder locks 2S and 29,respectively, will be operable by dierent keys, such as the keys Ll5 andle respectively, shown in Fig. 7. rl`he key may be termed the janitorskey, because in operating the cylinder lock 2S from the inside oi' thedoor, it will retract the latch bolt and stop it back in the case. Thekey 46 may be termed the teachers key, because when inserted in theoutside cylinder lock 29, it Will retract the latch bolt without,however, being operative'to stop it back in the case. By theconstruction describen, the actuation of the outside key in opening thedoor for entrance cannot alter the normally locked condition of the doorwhen the same is closed. lVhen it is desired to stop back the latch, thejanitor may readily do so by insertion of his key at the inside Withoutnecessitating the opening of the door. Moreover, When the teachers keywill not operate the inside cylinder lock, as in the 'form illustrated,manipulation of the detent mechanism for the latch bolt is confined tothe janitor alone, Which is desirable in some cases, but this is not anessential feature in all aspects of the invention. ln the forniillustrated the manually operable latch re tracting mechanism 16, 17,-at the inside or" the door, is similar in its function to the outsidecylinder lock in so tarV as it is incapable of operating the detentlever to stop back the latch bolt. Y

In the particular form shown, the latch bolt is dogged automatically onthe closing or' the door by means of a clogging lever i7 acted on by aspring 4:8 in such a manner that the head of such lever tends to lie inthe path of the latch bolt so as to block the i' incursion of the same.The lever 47 is held out of blocking position with respect to the latchbolt by a projecting controller bolt which is forced in by contact withthe strike so as to cause the bolt to be dogged by the lever.automatically on the closing or' the door. ln opening the door, aprojection 5f) on lever 2O engages a shoulder 51 on the tail of lever4:7 in such a manner as to swing the lever out of the path of the bolthead in the usual manner. In order to move thc. dogging lever out ofthepath orn the bolt when the latter vis to be retracted by the manualvretracting means at the inside oie the door,

the lever 16 acts on the lower extremity of i'io lll

the latch boltto be freely retracted. These features. in themselves areold inthe art, but it will be apparent thatfbythe constructiondescribed, the latch bolt may be rev-K' tracted by the manual retractlngmeans indefV pendently of the detent mechanism, and that thereafter thedetent mechanism may be moved by the rollback 27 toa position to dog`the bolt in the retracted position. In other Words, while the bolt isheld back by the depression of the thumb piece, it may be dogged inretracted position by one of the keys but notiby another key, said firstkey operating the detent leverindependently ,of Y
